Objectives:
This paper analyses the relationship between sociodemographic variables, executive dysfunctions, Sluggish Cognitive Tempo (SCT) and the mainly dimensions of ADHD: hyperactivity-impulsivity (ADHD-H/I) and inattention (ADHD-IN) in Brazilian adults.
Method:
A cross-sectional, exploratory, and comparative design was used. A total of 446 participants (295 women) aging from 18 to 63 years old (M = 3,499 years, SD = 10.7) were recruited on the internet. Correlations, t independent tests and regressions were conducted.
Results:
Higher scores in ADHD dimensions were associated to more executive functioning problems and time perception distortions in comparison to those participants without significant ADHD symptoms. However, ADHD-IN dimension as well as SCT were higher associated with these dysfunctions than ADHD-H/I. The regression results showed that ADHD-IN was more related to Self-Management to time while ADHD-H/I to Self-Restraint and SCT to Self-Organization/Problem Solving.
Conclusion:
This paper contributed to the distinction between SCT and ADHD in adults in important psychological dimensions.
